IMPROVEMENT IN LOOM-SHUTTLES.

Specification forming part of Letters Patent No. 134,971 dated January 2l, 1873.

To all whom it may concern:

Be it known that we, FRANCIS BLANDING and ANDREW J. BLANDING, both of Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain Improvements in Loom-Shuttles, of which the following is a specification:

Nature and Objects of the Invention.

The object of our invention is to reduce the amount of lilling or weft waste made in weaving, which we accomplish by an improved method of expanding the shuttle-spindle after the cop has been placed thereon, thereby holdin g the cop very firmly, and preventing it from being knocked oft' during the process of weaving.

In the accompanying drawing, Figure l is a longitudinal section through the middle of the shuttle, in which the spindle is shown by full lines when in the position which it occupies when weaving, andy the position of its lower endl when turned outward for the purpose of putting on the cop is shown by the dotted lines. Fig. 2 is a plan of the spindle. Fig. 3 is a section of the same.

A is the body of the shuttle, which, in its general construction, may be in any desired form. B is the spindle, split for a part of its length, as has been heretofore customary for cop-shuttles, and having the hole h and the groove g, through which the wedge C ,is inserted and slides. The sliding wedge C is arranged so as to be drawn back and forth within the spindle by means of its 'curved end coming in contact with the pin p and the body of the shuttle or the plate S which is fixed there- The operation is as follows: When a cop is to be putin the shuttle the spindle is turned outward in theusual manner. In doing this the wedge C is drawn backward from the point of the spindle by means of the pinp, i

Claim.

We claim as our inventiont The combination, with the shuttle-spindle, of the sliding wedge or pin C, so arranged as to be drawn back and forth within the spindle, substantially as and for the purpose specified.
